In order to prevent the effective foot length from changing when putting weight on the foot, the lower coupling element (8) extends to the heel area.

Description

The justice foot
Technical field
The present invention relates to a kind of adopted foot; It has the connector that is used for lower leg portion and has preceding heel piece; Should be connected with this connector radial type with following coupling element by last coupling element by preceding heel piece; Make the angle position of connector control the angle position of preceding heel piece, wherein, one of said coupling element extends in the foot heel zone of foot always.
Background technology
This adopted foot is described in formerly not disclosed German patent application DE 10 2,004 031 562 A1, quotes its disclosure.Because preceding heel piece is coupled through two coupling elements with the connector that is used for lower leg portion, carried out the pressure coupling aspect the angle position of connector and preceding heel piece first.The angle position of connector or lower leg portion is along with the change of buttocks causes preceding heel piece to lift in proportion.Therefore adopted foot can get into from the position (" position barefoot ") of no heel has the footwear of high heel, and thus, shank and connector change on the meaning with the hip angle displacement with respect to the position of the plantar surfaces of toe of adopted foot.Preceding thus heel piece lifts far away like this, so that it is parallel to bearing-surface (the preceding ends of footwear) again.Before heel piece therefore regularly at the standing surface upper support and bear necessity load that safety is stood required, even also be like this when having high heel.Therefore the soft or elastic construction of preceding heel piece that does not need previous regulation.
The adopted foot that the front is described preferably includes a plurality of hinge means, one or four hinge means especially, and wherein, the coupling element between the forward foot in a step and the middle foot areas can be parallel to each other basically.Obtain 1: 1 the coupling of angular movement of connector and preceding heel piece thus, this is ideal for adaptive height heels.Go up coupling element in the adopted foot of describing in front and extend in the foot heel zone, therefore be configured to a kind of rocking bar, roughly radial type is placed on the connector at the middle part for it.The advantage of this structure is that the rotary gemel of last coupling element roughly is placed in the position of nature ankle joint.But disadvantageously be, the load exercise that is configured to the last coupling element of rocking bar has changed the foot length of adopted foot in plantar region, so that for example undesirable foot possibly occur under the load and vacillate waving.
Summary of the invention
Therefore, task of the present invention is, reaches the advantage of the said type justice of beginning foot, changes owing to the motion of last coupling element and needn't stand foot length.
In order to solve this task, according to the present invention, the characteristics that start said type justice foot are that following coupling element wherein extends in the foot heel zone always.In according to adopted foot of the present invention, the motion of preceding heel piece does not cause the length variations of foot, so that has avoided because the shortcoming that the foot length variations is produced.Because the hinge of coupling element has the decision meaning down for the ankle motion of the present invention's justice foot; Can cause the position of the hinge of following coupling element according to advantage of the present invention a little less than the physiology ankle joint; Because from cosmetic reasons, obviously higher leg structure is undesirable.Must be the basis in this case with the compromise solution aspect the position of rotary gemel.
In addition; According to adopted foot of the present invention allow adaptive automatically before heel piece with respect to the angle position of adopted foot vola bearing-surface, this bearing-surface is next definite through the supporting-point " thenar " on the coupling element that constitutes on the junction point between pro-heel piece and the foot central region, " the foot heel " of calling in person on the regional rearward end through foot on the other hand on the one hand.In having the footwear of higher heel, this bearing-surface favours horizontal plane.Because lower leg portion must basic vertical orientation in order to obtain balance, the angle that generation one is reversed to buttocks between this infra coupling element and the connector that is used for lower leg portion.Before this angle is delivered to heel piece and be responsible for making before heel piece lift so that before heel piece directed abreast with respect to territory, the preceding base area face of ground or footwear, but thereby in forefoot region holding capacity, these power cause the high safety of standing.
As describe in front according to such in the structure of DE 10 2,004 031 562 A1, what can meet purpose is that construct on one of them variable-length ground, limited ground of coupling element.For walking, heel piece was disadvantageous before direct angular movement with ankle passed to.The conversion of preferably carrying out through the obliquity of coupling element, it converts the angular movement hypergeometric of ankle to the motion of preceding heel piece routinely.Need to carry out the length of one of them coupling element adaptive in order to compensate height heels in this case.This can carry out statically, thus only when changing footwear in order to adapt to height heels needs length adaptive.But dynamic length variations also is fine, and its mode is, one of them coupling element can flexibly extend or for example through the hydraulic cylinder adjustable length.
The intensive forward foot in a step that for example can reduce thus when center of gravity moves forward, to occur is loaded.If length variations can then produce the forward foot in a step counter-force that increases gradually against the effect of the elastic reaction that increases gradually, this hopes.At this, by stable, this is equivalent to the sensation of standing of nature to certain " the waving " when patient stands through counter-force elastic, that increase gradually.
The length variations of coupling element also can cause through a hydraulic cylinder, and preferably through such hydraulic cylinder: it only can be regulated through changing slowly, and locking under short-term load (duty).This hydraulic cylinder has illustrated in detail in DE 102,004 031 562 A1.
For walking dynamically advantageously, the relative motion between foot heel zone and the Connection Element is through vibration absorber decay.This vibration absorber should have the spring function of vibration damping at this, but also can preferably construct like this: make its respond static load, its mode is that hydraulic cylinder is provided with and streams mouth.Can carry out adaptation in this way, so that each standing place does not always stress and needn't overcome the counter-force that possibly exist and keeps to different height heels.
What can meet purpose is, the radial type of coupling element is fixing not to be to cause through rotary gemel, but the connection through spring.At this, the connection of this spring can be only at an end of this coupling element but can constitute at the two ends of this coupling element.
Of the present invention one especially preferred embodiment in, following coupling element through each leaf spring element spring abut in before on the heel piece with connector on, wherein, these two leaf spring element get in feet heel zones and there each other face recline.At this, the leaf spring element that is connected with Connection Element constitutes a C shape, and the leaf spring element that is connected with preceding heel piece has slight waveform.
Also be suitable for additional dynamic adjustment according to adopted foot of the present invention, at this dynamically in the adjustment, coupling element can be by continuous control aspect its damping behavior, for example has under the situation of hydraulic cylinder of the valve of can electricity regulating in use.This control can be carried out according to the location status of measured load condition and foot.

The specific embodiment
First embodiment according to foot of the present invention shown in Fig. 1 has a connection piece 1, it above that side be provided with prominent 2 of an adapter, the prominent head of this adapter is axial truncated cone shape on head.But prominent 2 of this adapter makes it possible to the piped lower leg portion that adjustment ground receives below-knee prosthesis.
Coupling element 3 is connected with this connector 1 through rotary gemel 4 on one.The other end that should go up coupling element is connected through another rotary gemel 5 and a preceding heel piece 6, through the toe region of this preceding heel piece natural imitation foot.On the pro-heel piece 6, another rotary gemel 7 is arranged below rotary gemel 5, through it, once coupling element 8 is connected with preceding heel piece 6.Following coupling element 8 is hinged on the bottom of connector 1 and has a prominent head through a rotary gemel 9, this prominent head surpasses continue the down foot heel end 10 of coupling element 8 freedoms of entry of rotary gemel 9, and foot that this prominent head stretches into foot is called in person in the zone.Therefore the end of foot heel freely 10 slightly folds downwards.Can see; Following coupling element 8 is with the heel end 10 of foot freely and two rotary gemels 7 of its back; 9 constitute a rocking bar, and this rocking bar for example lands in the foot heel when carrying out walking because ground drag and on the end 10 of foot heel freely, being loaded at foot, thereby preceding heel piece 6 is applied a torque; Through this torque, the upwards swing of preceding heel piece 6.The rotary gemel 9 of this rocking bar is equivalent to ankle joint.
Preceding heel piece 6 is configured to the wedge of a general triangular, and (unshowned) before its downside 11 is parallel in heel piece 6 zones is used for the bearing-surface of this foot.
In the embodiment shown in fig. 1, connector 1, coupling element 3,8 is constructed with preceding heel piece 6 rigidly.Heel piece 6 upwards rotated immediately before therefore load in foot heel 10 zones, end caused, and it is equivalent to toe and lifts.In order to relax this factitious reaction, in embodiment, a vibroshock 12 is set according to the variation of Fig. 2, it is placed between the foot heel end 10 of connector 1 and following coupling element 8.When loading with ground reaction force to foot heel end 10, vibroshock 12 for example is responsible for making the foot heel end 10 of back lingeringly and in case of necessity upwards to swing restrictedly, heel piece 6 phase delay ground and the upwards swing of restricted ground before causing thus.
Vibroshock 12 preferably is set to have the hydraulic cylinder that streams mouth, and this streams mouth is closed by too high flowing velocity.Can realize that thus for example when adopted foot was inserted in the footwear with higher heel, the angle position between the foot of connector 1 and back heel end 10 or the following coupling element 8 almost changed statically.In this way can adaptive connector 1 with respect to the angle position of coupling element 8 down; Thereby the lower leg portion of adaptive artificial limb is with respect to the angle position of following coupling element 8; So that infra coupling element 8 because heel is higher away from the time can realize the vertical orientation of lower leg portion, this vertical orientation needn't overcome elastic reactance and keep.
The angle position of following coupling element 8 is obtained by some bearing-surfaces in addition, and these bearing-surfaces are obtaining on the foot heel end 10 of back and on the thenar end 13 that is provided with rotary gemel 7 in front.
Also to mention, vibroshock 12 also with the foot heel end 10 of back be connected with connector 1 radial type.Can see corresponding rotary gemel 12 ' the connector 1 from Fig. 2.
In the embodiment shown in fig. 3, last coupling element 3 ' construct by hydraulic cylinder 14 variable-length ground.This embodiment helps adopted foot to adapt to different height heels.Descend coupling element 8 to be provided with prominent 15 in addition, it continues down coupling element 8 above each loads each compression spring and fixed backstop 17 synergism to a compression spring 16 in rotary gemel 7 entering one free end and in both sides.Following coupling element 8 is flexibly decayed by these compression springs 16 with respect to the swing of preceding heel piece 6 and by these backstops 17 restrictions, is excessively swung with heel piece 6 before avoiding.
In the 3rd embodiment according to foot of the present invention shown in Figure 4, connector 1 respectively is provided with an abutment face 18,19 with preceding heel piece 6, and a respective section of each leaf spring element 20,21 abuts on this abutment face and correspondingly is fixed on the there.These two leaf spring element 20,21 are combined into down coupling element 8, and therefore this time coupling element flexibly constructs.The leaf spring element 20 that is connected with connector 1 is C shape structure roughly; Realize elastic foot heel element simultaneously, promptly exercise with Fig. 2 in the similar function of vibroshock 12, the leaf spring element 21 that is connected with preceding heel piece 6 according to the form in vola in the past heel piece 6 to the foot end 10 waveforms extension of calling in person; In foot heel end; Two leaf spring element 20,21 face each other recline, and interconnect and constitute a free end jointly.
Because the moulding of leaf spring element 20,21 has produced the point of rotation 22,23.The point of rotation 22 is positioned near the connector 1 and bears ankle joint function, and the point of rotation 23 on the leaf spring element 21 is in the thenar zone of adopted foot.
Can see that in the embodiment shown in Fig. 1 to 4, the pendulum angle of preceding heel piece 6 is by control by force, but wherein effective foot length remains unchanged.
